2. Description of the Prior Art

People are always paying a great deal of attention on health developments. Many developments in medical technology are often targeted on treating diseases and prolonging human life. However, most of the treatments in the past are passive, which means the diseases are only treated as they occur. These methods include operation, medication, radiation therapy, chronic diseases care, rehabilitation, corrective therapy, or even medical treatments for cancers. In recent years, the research from medical experts has been gradually moving towards preventive medical methods, such as research on healthy food, screening and preventing inherited diseases, which actively prevents diseases from occurring in the future. Because of the focus on prolonging human life, many anti-aging and anti-oxidation technologies including skin care products and anti-oxidation food/medicine are gradually being developed and are becoming increasingly popular to the general public.

Studies have found that there are instable oxygen species (O+), also known as free radicals, in the human body. The free radicals are usually generated due to diseases, diet, environment and one's lifestyle, but they can be excreted in the form of water by reacting with the inhaled hydrogen. With this method, the amount of free radicals in the human body can be reduced, thereby restoring the body condition from an acidic state to an alkaline state, achieving an anti-oxidation, anti-aging and beauty health effect, and even eliminating chronic diseases. Furthermore, there are many clinical experiments showing that patients who need to inhale a high concentration of oxygen for an extended period of time would experience lung damage, and they could be ameliorated by inhaling hydrogen.

Hydrogen gas is generally generated through electrolyzing liquid water by an electrolytic apparatus for humans to breathe.
